Horizontal Scan Line Glitch Rendering issue
I’ve been noticing stubborn glitches that is just one dotted horizontal line through my video whenever I imported a Pro Res file into AE.
I also noticed a garbage of horizontal glitch in FCP as well. All these videos are in Pro Res. It also affected the other codec as well so no matter what I do, it keeps popping up!
What is happening here?

What I meant was, I’ve been doing the same work flow for all the projects that I’ve done such as
Converting all the raw h.264 to Pro Res HQ
So, I’ve been exporting all the edited videos to Pro Res HQ as always.
Then something went wrong through my last project which I noticed the glitches. You’re right about FCP being a problem first because today I exported my older project to Pro RES HQ and noticed a garbage of glitch. It wasn’t like that before so I have no idea what is going on here because it was working perfectly before.
However, I must mentioned this, we modified this IMAC by increasing the memory up to 16 GB MHz DDR3 and hooking up this new 8 TB RAID drive as a working drive. I used my last project with this new set up and the glitches began. But my tech guy said this shouldn’t be the problem, so I’m stumped.

I checked the quicktime file using the different machine and it also shows the glitch as well.
It doesn’t makes any sense because it was clean before with the same workflow. I’m talking everything before any computer modification.
Right now, I’m rendering the other project using AE CS 5.5 and played around with different codec such as animation and pro res HQ.
I noticed that the glitches got worse when I rendered it into a different drive comparing to the working drive.
My next step is to reinstall after effect so we’ll see what happen. I’ll take in your workflow suggestion for the next project.

It turned out that the Glitch was created by the memory ram.
Before the glitch happened, the computer was running off of an 8 GB 1067 MHz DDR3 and we beefed it up to 16 GB.
Looks like the 16 GB was flawed.
No MORE GLITCH!!!! YES, VICTORIOUS!

I had that same problem (even worst) when i render from AE CS6. It showed the worst as rendered AVI files, so i started rendering as QT and this helped a bit. In the end it was not a ram problem or codec problem. I started rendering to another drive and the problem went instantly thank God. So I don’t if it was a dive permission thing or what but that was my solution and it worked. So try switching render output to another drive.
This post might help someone else in the future with this problem
Peace
